Efficient Heritable Gene Expression Readily Evolves in RNA Pools.

ABSTRACT: Heritable gene expression arises readily in a simple non-genetic system employing known small-RNA biochemistry. Pooled cross-templating ribonucleotides show varied chemical competence on which selection acts, even calculating only minimal effects. Evolution can be quick-computed progress toward encoded gene expression can require only days or weeks for two millimolar, partly activated complementary 5' ribonucleotides. After only one product selection cycle, early templating can become prevailing pool behavior. Subsequently, a selected templated product is efficiently amplified as a pool ages, frequently accumulated in the same order of concentration as incoming nucleotides. Pools spontaneously favor templating because sporadic nucleotide accumulations increase it-and selection increases te
